Technical Field
[0001] The present invention relates to the field of communications, and particularly to
a resource configuration method, system and device for an SC-MCCH.
Background
[0002] Along with rapid development of Internet and popularization of large-screen multifunctional
mobile phones, a great deal of mobile data multimedia services and various high-bandwidth
multimedia services emerge, such as video conferencing, television broadcasting, video
on demand, advertising, online education, interactive games and the like. Multi-service
requirements of mobile users are met on one hand, and on the other hand, new service
growth points are also brought to mobile operating companies. These mobile data multimedia
services may require multiple users to simultaneously receive the same data. Compared
with ordinary data services, the mobile data multimedia services have the characteristics
such as large data volume, long duration and high time delay sensitivity.
[0003] In order to effectively utilize mobile network resources, the 3rd Generation Partnership
Project (3GPP) proposes a Multimedia Broadcast/Multicast Service (MBMS). The MBMS
is a technology of transmitting data from a data source to multiple target mobile
terminals to implement sharing of a network (including a core network and an access
network) resource and increase a utilization rate of the network resource (particularly
an air interface resource). The MBMS defined by the 3GPP may not only implement pure-text
and low-rate message multicast and broadcast but also implement high-speed multimedia
service broadcast and multicast to provide various video, audio and multimedia services.
The capability of the MBMS undoubtedly follows a tendency of future mobile data development
and provides a broader service prospect for development of a 3rd-Generation (3G).
[0004] The MBMS has the characteristics that a data volume of the service is large, a reception
duration of a mobile terminal is long and an average data rate is constant. These
characteristics decide that scheduling and control signaling configuration of the
MBMS are both semi-static, that is, scheduling information and control signaling information
of the MBMS are both kept unchanged for "a long time". The scheduling information
and control signaling information, which may be collectively referred to as MCCH information,
of the MBMS may be periodically sent through an MBMS Control Channel (MCCH). Multiple
MCCHs may be present in an Evolved MBMS (eMBMS) system. Each MCCH may correspond to
different MBMS Single Frequency Network (MBSFN) areas, and only bear MBMS control
information sent by the corresponding MBSFN area.
[0005] An MBMS notification message may be configured to describe whether MCCH information
changes or not. For User Equipment (UE) in an Radio Resource Control (RRC) idle state
or an RRC connected mode, whether MCCH information changes or not may be known by
monitoring an MBMS notification message, thereby implementing selective reception
of the MCCH information, that is, new MCCH information may be received only when the
MCCH information changes. Since an information amount of the MBMS notification message
is far smaller than the MCCH information, selective reception of the MCCH information
by the UE may effectively save resources and reduce power consumption. MCCH notification
information may be borne and periodically sent on a Physical Downlink Control Channel
(PDCCH) of a specified MBSFN subframe. The specified MBSFN subframe and a sending
period of the MCCH notification information may be indicated through a System Information
Block 13 (SIB13).
[0006] In a Long Term Evolution (LTE) system, for notifying session start of a specified
MBMS to UE (or called as a terminal) or initiating a counting request by a network
side, Downlink Control Information (DCI) and an MBMS-Radio Network Temporary Identifier
(M-RNTI) may be sent on a PDCCH at first. The UE may further read a specific MCCH
message according to related information in the DCI. This mechanism is called as an
MCCH change notification mechanism. A specific service configuration parameter, for
example, a service Identifier (ID), Radio Link Control (RLC) of the service Media
Access Control (MAC) and a physical-layer configuration parameter, may be sent on
an MCCH.
[0007] At present, an MBMS technology is introduced into a Release 9 (R9) LTE system, and
is enhanced in Release 10 (R10). In R9, control signaling and user data of an MBMS
may be separately transmitted in a Control Plane (CP) and a User Plane (UP) respectively.
The CP may control sending of UP data by controlling start, change and end of the
service, thereby implement basic MBMS sending. The MBMS may be sent in an MBSFN area
with a fixed size (which may be statically or semi-statically configured). In R10,
for increasing a resource utilization rate of an MBMS system and facilitating management
of an operating company, the MBMS technology is enhanced, mainly including counting
and a priority-based preemption mechanism.
[0008] The 3GPP proposes a research subject of single-cell MBMS in Release 13 (R13) LTE-Advance
(LTE-A). Fig. 1 is a schematic diagram of a single-cell MBMS. A single-cell MBMS may
be transmitted on a Physical Downlink Shared Channel (PDSCH).
[0009] A PDCCH may serve as indication information for parsing PDSCH data. Therefore, the
PDCCH may be sent before the PDSCH (data domain) in the time domain, that is, the
PDCCH may occupy the former 1-4 symbols of one subframe. Fig. 2 is a schematic diagram
of a channel on which a PDCCH occupies 3 symbols in one subframe. Information transmitted
in the PDCCH is called as DCI, which may be used for indicating information such as
a resource configuration of the PDSCH and an uplink resource grant. A Cyclic Redundancy
Check (CRC) at the tail of the PDCCH occupies 16-bit, and may be scrambled by adopting
a specific RNTI. The RNTI may be configured to identify UE or a specific use. The
UE may perform blind detection on the PDCCH of the received subframe. In the blind
detection, a descrambled bit sequence may be searched by the UE to obtain required
control signaling under the condition of no prior information. Blind detection has
the advantage of no additional overhead and the shortcoming of relatively high detection
complexity. For reducing searching complexity, the concept of search space is defined
in TS36.213. Each UE may search a specific search space for control information, and
each search space may include a group of Control Channel Elements (CCEs). A search
space in LTE includes a common search space and a UE-specific search space.
[0010] In a research and practice process, the inventor finds that the related technology
has the following problems. Single-cell MBMS scheduling and multi-cell MBMS (MBSFN)
scheduling may be greatly different in that an SC-MCCH is borne and sent on a PDSCH,
while an MCCH of an MBSFN area is borne and sent on a Physical Multicast Channel (PMCH).
There is yet no method applicable to resource configuration of an SC-MCCH.
[0011] For the problem that there is no resource configuration method applicable to an SC-MCCH,
there is yet no effective solution.
Summary
[0013] Some embodiments of the present invention provide a resource configuration method,
system and device for an SC-MCCH, which may at least solve a problem that there is

[0047] An embodiment provides a resource configuration method for an SC-MCCH. Fig. 4 is
a first flowchart of a resource configuration method for an SC-MCCH according to an
embodiment of the present invention. As shown in Fig. 4, the flow may include the
following act.
[0048] At act S302, UE may receive a system broadcast message sent by a base station. The
system broadcast message may contain configuration information of the SC-MCCH configured
by the base station. The configuration information may include an MP of the SC-MCCH,
time-domain location information of the SC-MCCH and an MCS of the SC-MCCH, and the
configuration information may further include at least one of: an RP of the SC-MCCH,
configuration information of SC-MCCH change notification information, and a value

[0049] By the act, the UE may receive the system broadcast message sent by the base station.
The system broadcast message may contain the configuration information of the SC-MCCH
configured by the base station, that is, the base station may configure the configuration
information of the SC-MCCH in the system broadcast message. By virtue of the solution,
a problem that there is no resource configuration method applicable to the SC-MCCH
is solved, and resource configuration of the SC-MCCH is implemented.
[0050] In the embodiment of the present invention, the MP may be used for indicating a period
of modification of the SC-MCCH. The RP may be used for indicating a period of repeated
sending of the SC-MCCH in one MP. The time-domain location information of the SC-MCCH
may be used for indicating locations of a radio frame and/or radio subframe where
the SC-MCCH is located. The MCS may be an MCS of the radio subframe where the SC-MCCH
is located. The configuration information of the SC-MCCH change notification information
may be used for indicating time-domain location information of the SC-MCCH change
notification information. Herein, the time-domain location information of the SC-MCCH
change notification information may include: locations of a radio frame and radio
subframe where the SC-MCCH change notification information is located. The value tag
may be used for indicating the SC-MCCH change notification information.
[0051] In the embodiment of the present invention, under a condition that the configuration
information includes the configuration information of the SC-MCCH change notification
information, the SC-MCCH change notification information may be indicated by DCI in
a PDCCH. Under a condition that the configuration information includes the value tag,
the SC-MCCH change notification information may be indicated by the value tag.
[0052] In the embodiment of the present invention, after the act that the UE receives the
system broadcast message sent by the base station, the method may further include
the following acts. The UE may determine whether the SC-MCCH changes or not according
to the configuration information. Under a condition that the SC-MCCH changes, the
UE may read changed SC-MCCH information.
[0053] In the embodiment of the present invention, under a condition that the SC-MCCH change
notification information is indicated by the value tag, the act that the UE determines
whether the SC-MCCH changes or not according to the configuration information may
be implemented in the following manner. The UE may compare a value of the value tag
and a value of a value tag locally stored by the UE. Under a condition that the value
of the value tag is different from the value of the value tag locally stored by the
UE, the UE may determine that the SC-MCCH changes. Under a condition that the value
of the value tag is the same as the value of the value tag locally stored by the UE,
the UE may determine that the SC-MCCH does not change.
[0054] In the embodiment of the present invention, under a condition that the SC-MCCH change
notification information is indicated by the DCI, the act that the UE determines whether
the SC-MCCH changes or not according to the configuration information may be implemented
in the following manner. The UE may read the configuration information of the SC-MCCH
change notification information in the configuration information. The UE may monitor
the SC-MCCH change notification information at a location, indicated by the configuration
information of the SC-MCCH change notification information, of the subframe where
the SC-MCCH is located. The UE may determine whether the SC-MCCH changes or not according
to the SC-MCCH change notification information.
[0055] The term monitoring in the embodiment of the present invention may refer to a following
process. The UE may perform a mask operation by adopting an SM-RNTI and a CRC of a
subframe of an SC-MCCH change notification message, and check the CRC. In case of
successful checking, the UE may determine that the subframe is a required subframe,
and further read a content of the DCI in the PDCCH of the subframe, the content of
the DCI being the SC-MCCH change notification message.
[0056] In the embodiment of the present invention, the act that the UE determines whether
the SC-MCCH changes or not according to the SC-MCCH change notification information
may be implemented in the following manner. The UE may acquire a value of a first
specified bit N in the DCI, where the value of N may be 1 or 0. Under a condition
that N is 1, the UE may determine that the SC-MCCH changes. Under a condition that
N is 0, the UE may determine that the SC-MCCH does not change.
[0057] In the embodiment of the present invention, after the act that the UE determines
whether the SC-MCCH changes or not according to the configuration information, the
method may further include the following acts. The UE may determine whether a service
of the SC-MCCH changes or not according to the DCI. Under a condition that the service
of the SC-MCCH changes, the UE may receive changed SC-MCCH information.
[0058] In the embodiment of the present invention, the act that the UE determines whether
the service of the SC-MCCH changes or not according to the DCI may be implemented
in the following manner. The UE may acquire a value of a second specified bit M in
the DCI, where the value of M may be 1 or 0. Under a condition that M is 1, the UE
may determine that a PS service of the SC-MCCH changes. Under a condition that M is
0, the UE may determine that an ordinary service of the SC-MCCH changes.
[0059] In the embodiment of the present invention, the act that the UE reads the changed
SC-MCCH information may be implemented in the following manner. The UE may read the
changed SC-MCCH information at a start time of a next MP according to the time-domain
location information of the SC-MCCH.
[0060] From the above descriptions about implementation modes, those skilled in the art
may clearly know about that the method according to the abovementioned embodiments
may be implemented in a manner of combining software and a universal hardware platform,
and of course, may also be implemented through hardware. However, the former is an
exemplary implementation mode under many circumstances. Based on such an understanding,
the technical solutions of the present invention substantially or partially making
contributions to a conventional art may be embodied in form of software product. The
computer software product may be stored in a storage medium (for example, a Read-Only
Memory (ROM)/Random Access Memory (RAM), a magnetic disk and an optical disk), including
a plurality of instructions configured to enable terminal equipment (which may be
a mobile phone, a computer, a server, network equipment or the like) to execute the
method of each embodiment of the present invention.
[0061] An embodiment provides a resource configuration system for an SC-MCCH. Fig. 5 is
a resource configuration system for an SC-MCCH according to an embodiment of the present
invention. As shown in Fig. 5, the system may include a base station 42 and UE 44.
[0062] The base station 42 may be configured to send a system broadcast message to the UE.
The system broadcast message may contain configuration information of the SC-MCCH
configured by the base station. The configuration information may include an MP of
the SC-MCCH and time-domain location information of the SC-MCCH, and the configuration
information may further include at least one of: an RP of the SC-MCCH, configuration
information of SC-MCCH change notification information, and a value tag.
[0063] The UE 44 may be configured to receive the system broadcast message sent by the base
station 42, determine whether the SC-MCCH changes or not according to the configuration
information, and under a condition that the SC-MCCH changes, read changed SC-MCCH
information.
[0064] By the system, the base station may send the system broadcast message containing
the configuration information of the SC-MCCH configured by the base station, that
is, the base station may configure the configuration information of the SC-MCCH in
the system broadcast message, and then the base station may send the system broadcast
message containing the configuration information to the UE. By virtue of the solution,
a problem that there is no resource configuration method applicable to the SC-MCCH

notification information is indicated by the value tag, when a value of the value
tag is different from a value of a value tag locally stored by UE, it may be indicated
that the SC-MCCH changes; and when the value of the value tag is the same as the value
of the value tag locally stored by the UE, it may be indicated that the SC-MCCH does

information, the SC-MCCH change notification information may be indicated by DCI in
a PDCCH. Under a condition that the configuration information includes the value tag,

not change.
[0078] In the embodiment of the present invention, under a condition that the SC-MCCH change
notification information is indicated by the DCI, when the SC-MCCH change notification
information only indicates whether the SC-MCCH changes or not, a first specified bit
N in the DCI may be used for indicating whether the SC-MCCH changes or not, wherein
a value of N is 1 or 0, and N being 1 may indicate that the SC-MCCH changes while
N being 0 may indicate that the SC-MCCH does not change. In the embodiment of the

[0079] In the embodiment of the present invention, the SC-MCCH may be identified by a first
RNTI; and the SC-MCCH change notification information may be identified by a second
RNTI.
[0080] Still another embodiment provides a resource configuration device for an SC-MCCH.
Fig. 7 is a first structure block diagram of a resource configuration device for an
SC-MCCH according to an embodiment of the present invention. As shown in Fig. 7, the
device is applied to UE, and the device may include a receiving module 62.
[0081] The receiving module 62 may be configured to receive a system broadcast message sent
by a base station. The system broadcast message may contain configuration information

[0082] By the act, the base station may send the system broadcast message containing the

the base station may configure the configuration information of the SC-MCCH in the
system broadcast message. By virtue of the solution, a problem that there is no resource
configuration method applicable to the SC-MCCH is solved, and resource configuration
of the SC-MCCH is implemented.
[0083] In the embodiment of the present invention, the MP may be used for indicating a period
of modification of the SC-MCCH. The RP may be used for indicating a period of repeated
sending of the SC-MCCH in one MP. The time-domain location information of the SC-MCCH

information, the SC-MCCH change notification information may be indicated by DCI in
a PDCCH. Under a condition that the configuration information includes the value tag,
the SC-MCCH change notification information may be indicated by the value tag.
[0085] Fig. 8 is a second structure block diagram of a resource configuration device for
an SC-MCCH according to an embodiment of the present invention. In the embodiment
of the present invention, the device may further include a determination module 72
and a reading module 74. The determination module 72 may be configured to determine

change notification information.
[0088] Fig. 9 is a third structure block diagram of a resource configuration device for
an SC-MCCH according to an embodiment of the present invention. As shown in Fig. 9,
in the embodiment of the present invention, the determination module 72 may include

[0090] The first acquisition unit 726 may further acquire a value of a second specified

that M is 1, that a PS service of the SC-MCCH changes, and determine, under a condition

M may be 1 or 0.
[0091] The reading module 74 may be further configured to read the changed SC-MCCH information
at a start time of a next MP according to the time-domain location information of
the SC-MCCH.
[0092] Each module may be implemented through software or hardware, and the latter condition
may be implemented in, but not limited to the following manners. The modules may all
be located in the same processor, or, the modules may be located in multiple processors
respectively.
[0093] For better understanding the present invention, the present invention may further
be explained below in combination with an exemplary embodiment.
[0094] The exemplary embodiment provides a configuration method for an SC-MCCH, which may
include the following act. Configuration information of the SC-MCCH may be indicated
on a Single Cell-Point to Multi-point (SC-PTM) cell broadcast message. The configuration
information may include an MP of the SC-MCCH, time-domain location information of
the SC-MCCH and an MCS of the SC-MCCH, and the configuration information may further
include at least one of an RP of the SC-MCCH, configuration information of SC-MCCH
change notification information, and a value tag.
[0095] Fig. 10 is a flowchart of a configuration method for an SC-MCCH according to an exemplary
embodiment of the present invention. As shown in Fig. 10, the method may include the
following acts.
[0096] At act 801, a base station, e.g., an evolved Node B (eNB), may send a system broadcast
message containing configuration information of an SC-MCCH.
[0097] The eNB may refer to an eNB where a cell sending an SC-PTM service is located. The
SC-MCCH is a single-cell multicast control channel, and the SC-MCCH may be used for
indicating related configuration information of an SC-MTCH. The configuration information
may be related configuration information of the SC-MCCH. The configuration information
may include an MP of the SC-MCCH, time-domain location information of the SC-MCCH
and an MCS of the SC-MCCH, and may further include at least one of: an RP of the SC-MCCH,
configuration information of SC-MCCH change notification information, and a value
tag.
[0098] The MP may indicate a period where the SC-MCCH may be modified, and the MP may be
one of {320ms, 640ms, 1,280ms, 2,560ms, 5,120ms, 10,240ms}. The RP may indicate a
period of repeated sending of the SC-MCCH in one MP, and the RP may be one of {160ms,
320ms, 640ms, 1,280ms, 2,560ms}. A time-domain location of the SC-MCCH may include
radio frame and radio subframe configuration information of the SC-MCCH, i.e. a radio
frame and radio subframe where the SC-MCCH is located. In the embodiment, the subframe
may be a unicast subframe. The MCS of the SC-MCCH may be an MCS of the subframe where
the SC-MCCH is located, and may be indicated by an index number corresponding to the
MCS.
[0099] The MP and the RP may adopt smaller numerical values according to a requirement,
but the following condition is suggested to be met. The MP is suggested to be larger
than a value of the RP.
[0100] The SC-MCCH change notification information may be indicated by any one of the following
methods: 1) a value tag; and 2) DCI in a PDCCH.
[0101] If the value tag is adopted for indication, an integer field sc-mcchValueTag may
be set in the system broadcast message indicating a configuration of the SC-MCCH,
a value of the field being (0...31). Every time when the SC-MCCH changes, the eNB
may set a new sc-mcchValueTag=original sc-mcchValueTag+1, the UE may store a value
of the sc-mcchValueTag every time when the UE reads the configuration information
of the SC-MCCH. If the UE finds that a value of sc-mcchValueTag in a current system
broadcast message is different from the locally stored value of the sc-mcchValueTag,
it is indicated that the SC-MCCH changes, otherwise it is indicated that the SC-MCCH
does not change.
[0102] If the DCI is adopted for indication, a specific RNTI, for example, SM-RNTI=FFFC,
may be allocated to the SC-MCCH change notification information at first. Considering
that the SC-MCCH is transmitted through a PDSCH and is scheduled through the PDCCH
on a frequency domain, it is suggested to pre-allocate an RNTI, for example, SC-MCCH
RNTI=FFFB, to the SC-MCCH, which may alternatively be SM-RNTI=FFFB and SC-MCCH RNTI=FFFC.
The time-domain location information, for example, a time-domain frame location and
a subframe index, for sending of the SC-MCCH change notification information and a
notification information repetition frequency in one MP of the SC-MCCH may be indicated
in the configuration information of the SC-MCCH change notification information on
the system broadcast system.
[0103] Specifically, when an SC-MCCH change notification information is borne on the DCI
in the PDCCH of the time-domain subframe, DCI format-1c may be adopted. If the notification
message only indicates whether the SC-MCCH changes or not, a bit N in the DCI may
be adopted for indication, it is indicated that the SC-MCCH will change in a next
MP of the SC-MCCH if N=1, and it is indicated that the SC-MCCH does not change if
N=0. A service type may be indicated in the DCI, for example, two bits N may be adopted
for indication, wherein N1 indicates whether the SC-MCCH changes or not, and N2 indicates
a changing service type. For example, N2=1 may indicate that a PS service changes,
and N2=0 may indicate that an ordinary service changes. Optionally, more than two
bits in the DCI may be adopted to indicate more change information.
[0104] The system broadcast message may be an existing system broadcast message, for example,
an SIB13 or an SIB15, or a newly created system broadcast message dedicated to an
SC-PTM. If the system broadcast message is the SIB13, the related configuration information
of the SC-MCCH may be added on the basis of a conventional of the existing SIB13.
[0105] At act 802, UE may receive SC-MCCH information.
[0106] The UE may monitor and receive required SC-MCCH information at a corresponding location
according to an indication of the configuration information of the SC-MCCH in the
system broadcast message. The UE may read the SC-MCCH information after startup or
cell reselection/handover to a new cell, and may also monitor the SC-MCCH change notification
information according to the configuration information of the SC-MCCH change notification
information.
[0107] Frequency-domain scheduling information of the SC-MCCH may be sent through the PDCCH
of the corresponding subframe, and specifically, may be sent through the DCI in the
PDCCH.
[0108] The DCI may at least include: scheduling information of the SC-MCCH on the frequency
domain. The UE may detect the subframe, indicated in the system message, of the SC-MCCH
by adopting the pre-allocated SC-MCCH RNTI, and in case of successful detection, it
may represent that the subframe includes the required SC-MCCH information.
[0109] The UE in the embodiment has an MBMS receiving capability, and may be interested
in receiving an MBMS. The UE may be in an RRC-connected mode or an RRC-idle mode.
[0110] At act 803, the UE may determine whether the SC-MCCH changes or not, if YES, act
804 is executed, otherwise act 805 is executed.
[0111] The UE may detect the PDCCH at the subframe location, indicated in the system broadcast
message, of the SC-MCCH change notification information. The detection may be implemented
in the following manner. A mask operation may be performed on a CRC of the subframe
by adopting the SM-RNTI, the CRC may be checked, in case of successful checking, it
is determined that it is a required PDCCH. In this situation, the UE may further read
a content of the DCI in the PDCCH. If the bit N corresponding to the SC-MCCH change
notification information in the DCI is 1, it may be indicated that the SC-MCCH will
change in the next MP, and if N=0, it may be indicated that the SC-MCCH will not change.
[0112] At act 804, the UE may read changed SC-MCCH information.
[0113] The UE may immediately read the changed SC-MCCH information at the beginning of the
next MP of the SC-MCCH according to the SC-MCCH time-domain location information indicated
in the system broadcast message.
[0114] At act 805, the UE may receive a required service according to existing SC-MCCH information.
[0115] The UE may read SC-MTCH time-domain configuration information in the existing SC-MCCH
information, and may further read required SC-MTCH data according to the time-domain
configuration information.
First embodiment
[0116] A scenario of the embodiment is that SC-MCCH change notification information is indicated
by DCI. Fig. 11 is a flowchart of a first embodiment of the present invention. As
shown in Fig. 11, the example may include the following acts.
[0117] At act 901, a base station, e.g., an evolved Node B (eNB), may indicate configuration
information of SC-MCCH change notification information through a system broadcast
message.
[0118] The system broadcast message may be an existing MBMS system message, for example,
an SIB13 or an SIB15. An SC-MCCH may be an MCCH corresponding to SC-PTM. The configuration
information of the SC-MCCH change notification information may be time-domain location
information of the SC-MCCH change notification information. A time-domain location
may include: a frame period, a subframe location and a change notification repetition
frequency in an MP of the SC-MCCH.
[0119] If DCI is adopted for indication, a specific RNTI, for example, SM-RNTI=FFFC, may
be allocated to the SC-MCCH change notification information at first. Considering
that the SC-MCCH is transmitted through a PDSCH and is scheduled through a PDCCH on
a frequency domain, it is suggested to pre-allocate an RNTI, for example, SC-MCCH
RNTI=FFFB, to the SC-MCCH, which may also be SM-RNTI=FFFB and SC-MCCH RNTI=FFFC. The
time-domain location information for sending of the SC-MCCH change notification information
may be indicated in the configuration information of the SC-MCCH change notification
information on the system broadcast system. The time-domain location information may
include: a time-domain frame period, a subframe location and a notification information
repetition frequency in an MP of the SC-MCCH.
[0120] At act 902, UE may read the configuration information of the SC-MCCH change notification
information.
[0121] The UE may read the configuration information of the SC-MCCH change notification
information in the system broadcast message.
[0122] At act 903, the UE may monitor the SC-MCCH change notification information.
[0123] The UE may perform monitoring at the subframe location indicated by the system broadcast
message. The monitoring may be implemented in the following manner. The UE may perform
a mask operation by adopting an SM-RNTI and a CRC of a subframe, check the CRC, and
in case of successful checking, determine that it is a required subframe. In this
situation, the UE may further read a content of the DCI in the PDCCH of the subframe.
The content of the DCI may be the SC-MCCH change notification information.
[0124] At act 904, the UE may determine whether the SC-MCCH changes or not, if YES, act
905 is executed, otherwise act 906 is executed.
[0125] Specifically, the SC-MCCH change notification information may be borne on the DCI
in the PDCCH of the time-domain subframe. The DCI format-1c may be adopted. If the
notification message indicates whether the SC-MCCH changes or not by adopting a bit
N in the DCI, it may be indicated that the SC-MCCH will change in a next MP of the
SC-MCCH if N=1, and it may be indicated that the SC-MCCH does not change if N=0.
[0126] At act 905, the UE may read changed SC-MCCH information.
[0127] The UE may immediately read the changed SC-MCCH information at the beginning of the
next MP of the SC-MCCH according to the SC-MCCH time-domain location information indicated
in the system broadcast message. Furthermore, the UE may read a required SC-MTCH content
according to the changed SC-MCCH information.
[0128] At act 906, the UE may receive a required SC-MTCH service according to existing SC-MCCH
information.
Second embodiment
[0129] A scenario of the embodiment is that SC-MCCH change notification information is indicated
by a value tag. Fig. 12 is a flowchart of a second embodiment of the present invention.
As shown in Fig. 12, the example may include the following acts.
[0130] At act 1001, a base station, e.g., an evolved Node B (eNB), may indicate configuration
information of SC-MCCH change notification information through a system broadcast
message.
[0131] The system broadcast message may be an existing MBMS system message, for example,
an SIB13 or an SIB15. An SC-MCCH may be an MCCH corresponding to SC-PTM. The value
tag may be an integer field sc-mcchValueTag set in the system broadcast message indicating
a configuration of the SC-MCCH, a value of the field being (0...31), that is, the
field may adopt all integer values between 0 and 31. Every time when the UE reads
the configuration information of the SC-MCCH, the UE may store a value of the sc-mcchValueTag.
If the UE finds that a value of sc-mcchValueTag in a current system broadcast message
is different from the locally stored value of the sc-mcchValueTag, it may be indicated
that the SC-MCCH changes, otherwise it may be indicated that the SC-MCCH does not
change.
[0132] At act 1002, UE may receive SC-MCCH information and a value tag of the SC-MCCH change
notification information.
[0133] According to an indication of the system broadcast message, the UE may receive the

message.
[0134] At act 1003, the UE may determine whether an SC-MCCH changes or not, if YES, act
1004 is executed, otherwise act 1005 is executed.
[0135] The UE may determine whether the SC-MCCH changes or not according to the locally

Third embodiment
[0139] A scenario of the embodiment is that SC-MCCH change notification information includes
service type information. Fig. 13 is a flowchart of a third embodiment of the present
invention. As shown in Fig. 13, the example may include the following acts.
[0140] At act 1101, a base station, e.g., an evolved Node B (eNB), may indicate configuration
information of SC-MCCH change notification information through a system broadcast
message.
[0141] The act is the same as act 901, and will not be elaborated herein.
[0142] At act 1102, UE may read the configuration information of an SC-MCCH change notification.
[0143] At act 1103, the UE may monitor the SC-MCCH change notification.
[0144] The act is the same as act 903, and will not be elaborated herein.

1105 is executed, otherwise act 1107 is executed.
[0146] The act is the same as act 904, and will not be elaborated herein.
[0147] At act 1105, the UE may determine whether a required service changes or not, if YES,
act 1106 is executed, otherwise act 1103 is executed.
[0148] SC-MCCH change notification information may indicate more service change related
information by adopting two or more bits. That is, a service type may be indicated
in DCI, and for example, two bits N are adopted for indication, wherein N1 may indicate
whether the SC-MCCH changes or not, and N2 may indicate a changing service type, for
example, N2=1 may indicate that a PS service changes, and N2=0 may indicate that an
ordinary service changes. Furthermore, more than two bits in the DCI may be adopted
to indicate more change information.
[0149] If the change notification is indicated through the two bits, the UE may determine
the changing service type according to a value of N2. If the UE is only interested
in a PS service, there is made such a hypothesis that N1=1, that is, the SC-MCCH changes.
When N2=1, it is indicated that the PS service changes and the UE may read changed
SC-MCCH information, and when N2=0, it is indicated that a non-PS service changes
and the UE may not read changed SC-MCCH information.
[0150] At act 1106, the UE may receive changed SC-MCCH information.
[0151] The act is the same as act 905, and will not be elaborated herein.
[0152] At act 1107, the UE may receive a required SC-MTCH service according to existing
SC-MCCH information.
